PAVING CONSTRUCTION.

Application filed December 11, 1922. Serial No. 606,022.

To all whom it may concern:

Be it known that I, ANTHONY MANeA- NrnLLo, a citizen of the UnitedStates, and a resident of Vest Pittston, county of Luzerne, State ofPennsylvania, have invented certain new and useful Improvements inPaving Constructions, of which the following is a specification,reference being had to the accompanying drawings.

My invention relates to improvements in the laying, replacement andrepair of roadway pavements;

A principal object of m invention is to provide means to facilitate thelaying, repair and replacement of block pavements particularly where thepavement is adjacent to and between street railway tracks.

A further object of my invention is to pro vide an improved pavementconstruction for use at street intersections and grade crossings wherethe rebuilding or re-laying of street railway or railroad tracks isfrequently necessitated by reason of the wear to which the rails aresubjected at such points.

A further object of my invention is to provide a pavement constructionwhich may be removed and replaced in a minimum amount of time wherebythe inconvenience, annoyance and obstruction to traffic is greatlyreduced.

A further object of my invention is to provide a series of supports forthe pavement blocks, the units of which are independently removable andinterchangeable.

The invention further includes all of the other various objects andnovel features of construction and arrangement hereinafter 1 moredefinitely specified and described.

In the accompanying drawings, Fig. 1 is a fragmentary top plan view ofone embodiment of my improvement; Fig. 2 is a transverse section takenon the line 2-2 of Fig. 1, the lifting device hereinafter referred tobeing also shown; Fig. 3 is a side'elevation partly shown in section;Fig. 4 is a detail end elevation of a supporting plate or n1en1- berused between the rails of a track; Fig. 5 is a side elevation of theplate or member shown in Fig. 4; Fig. 6 is a transverse section on theline 6-6 of Fig.4; Fig. 7 is a plan view of the lifting device and Fig.8 is a side elevation, partially shown in section, of the liftingdevice. 7

Like numerals refer to like parts in the several figures.

Rails 1 and 2 are the usual rails of a street railway or a railroadtrack which rest upon the usual sleepers or ties 3. A supporting plateor member 4, which may preferably be cast from iron, is ofa widthslightly less than the width between the rails 1 and 2 and comprises abottom 5 strengthened on its under side by ribs 6 which meet orintersect ribs 7 extending transversely thereto the ends of which arecut away as at 9 so as to fit the bases of the rails 1 and 2. Itibs orflanges 1O slightly spaced from the side edges of the plates. 4 extendupwardly therefrom to a height preferably of the thickness of the blocks11 which form the pavement. have found it desirable to spread a cushionof sand 12, say in thickness, upon the top of the plate 4 upon which thepaving blocks may rest. Means at the ends of the plates 4 for assistingin retaining the sand are provided by thevmembers 13 formed integrallywith the plates, projecting upwardly therefrom slightly and joining attheir ends the ribs 10.

It is desirable and in many instances essential that the block pavementbe installed outside of the rails, and I have provided new and usefulmeans therefor consisting 8 of supporting members or plates 14,preferably metal castings, comprising a bottom 15, a depending flange 16and side ribs or flanges 17 extending upwardly to a height preferably ofthe thickness of the blocks 11. Means 18 similar to members 13 are pro-In practice, I

vided at the ends of plates 14, join at their ends the ribs 17 andassist in retaining the sand upon the plates 14. Within the flanges 16are provided suitable holes for registry with holes in the web 19 of therails and through which are passed bolts 20 whereby the supportingmembers 14 are securely held in place. The length of the supportingplate 14 is preferably the same as that of the supporting member 4 sothat when assembled their ends will be in alignment. The flange 16extends along the web of the rail resting upon the base 21 thereof, andtransverse strengthening ribs 22 depend from the plates 14 being cutaway at their inner ends as at 23 so as to fit the bases of the rails.Support for the members 14 is provided by pillars of concrete 24 orother suitable means upon which the strengthening ribs 22 rest.

It will now be seen that I have provided an efficient means which may bequickly operated for the laying, removingand replacement of blockpavements- In operation, the plates 4: are interposed between therailsand are supported thereby, the ribs 7 resting upon the base of the railat three points; the sand is then spread over the upper surface of theplate to a suitable thick ness (although it will be understood that thesand is not necessary to the successful use of my improvement) and theblocks 11 are then suitably disposed upon the top of the said member atand within the ribs 10 and the projecting members 13. The plateslatextending outside of the rail are then placed in position and thesand and paving blocks placed therein.

I have also provided means whereby the supporting plates and thepavement carried thereby'may be speedily removed when for any reasonthat is required in connection with the repair or replacement of theblocks. or the re-building or re -laying of the rails of the track. Myimproved means for this purpose comprises a metal bar having flanges 26and 27 depending substantially three inches fromthe ends thereof, thelength of the bar being substantially the distance between the centersofthe headsof the rails 1 and 2' when positioned to form the track. Nearone end26 of the bar 25 I provide a hole 28, the end of the bar beingslightly thickened at this point, through which passes the bolt 29 thescrew threaded end of which passes into the screw threaded opening 30formed in'the edge of the supporting plate 4. It will be understood thatone or more of theselifting devices may be used as desired for eachsupporting plate and that a suitable number of holes 30 may becorrespondi-ngly provided. The lifting device is utili-zedby placing thelower edge of the flange 27 upon the head of the rail 2 and the loweredge of the flange 26 upon the head of the rail 1. The screw threadedend of the boll 29 is then caused to engage with the screw threadedopening 30 and the rotation of the bolt then causes the adjacent side ofthe supporting plate 4 to be lifted until it reaches a point above thehead of the rail 1, thereby permitting this end of the plate to begrasped and lifted by any suitable means, manually or otherwise. and theentire plate and the paving blocks and sand carried thereby to beremoved. 'It will be readily understood that by removing the bolts 20the supporting plates 14 on the outsid'eof the I do not desire thereforeto be limited or restricted to the exact details of construction andarrangement shown and described.

Having thus described my invention, I claim and desire to protect byLetters Patent of the United States:

1. A pavement construction adapted for railway tracks comprising a metalplateof a width slightly less than the distance between the railsandremovably positioned therebetween, paving material upon said i1plate, ribs extending longitudinally along the bottom of the plateandribs extending transverselythereto, the ends of saidlastmentionedribs being adapted'to fit the-bases of said rails and providing asupport for said plate.

2. Apavement constructionadapted for railway tracks comprising a plateremovably positioned between the rails, alayer of sand upon said plate,blocks of paving material upon said sand, said plate being provided withflanges extending along the sides thereof for retaining said blocks andsaid sand, andribs extending across the bottomof said plate, the endsofsaid ribs being adapted to engage the bases of said rails and to provide'support for said plate.

3. A pavement constructionadapted for railway tracks con'iprising aplate "removably positioned between the ltlllSy-Ei layer ofsanduponsaid. plate, blocks of paving material upon said'sand, said platebeing provided with-flanges extending along the sides thereof forretaining said blocks and said sand, means projecting from the platealong the ends thereof for retainingsaid sand, ribs extending across thebottom of said plate, the ends of said ribs beingadapted to engage thebases of said-rails and to provide support for said plate.
